Be it known. 'rhat 1, Burn sen of the Unified States. residing in thecity of Uolunihus, in the county of Franklin and State of Ohio, haveinvenied oer new V. Sacr a. eitiand hififlll Improvements in SliiieningMembers for Car Sides; and l do hereby declare the following to he afull, clear. and exact desrription of the inrension, such as Will enableothers skilled in the art to which it apperlains to make and use thesame.

My invention relates to stiffening members for cars. such as the sidestakes, end braces, side members. a.. and my object is to pro- (lureljhe same by a eheap and simple method whereby the distribution of themetal in rross-seethm is economical, practiral and Wei adapted toproduce the results desired.

When tmuglrshaped stakes or end braces are used in ear eonsi'rurion, lfind is desiralile to thirken the apex portion in order to increase thestrenglih and rigidity at this point ol grealesi stress.

To lhis end l1l invention consists generally in making ear still'eninglllllllllmls of trough-shape having a thiek-ei'ied apex portion andintegral outwardly extending hinges along their side edges, hy firstrolling a. substantially {at or rounded V shaped plate or l ar with aventrally ihirhened porlion extending longitiulinally thereof. thenHitting the liar or plate inlo the desired lengths. and llien shapingihese lengths holween forming (lies to romplete the operaliion.

Having thus given this general descriplion of my invention, l will now,in order to make the same more clear. refer to the aerompanying onesheet of drawings forming pal-l. ol' lhis spevilivaliion and in whichsizni lar (-liararlm's ol' relerenre designate like parls.

Fig. 6 illustrates the manner ofrolling the plate from which the sliffeners are made showing thefinishing pass in the rolls. Fig. 7 illustrates in cross-section thedies enu loyecl in pressing the plate or bar of metal so as to form myimproved stilleners, this view showing a plate of metal formed. intoshape between the (lies. Fig. 8

is a side elevation of an end brace having' a straight attaching flangedface. Fig. 9 shows in side elevation an offset end portion of one of theend braces adapted to ill; over a corresponding projection on the ear.Fig. 10 illustrates in front and side elevations another form of earstake having a tapered trouglnshaped rib running longitudinally thereof.this form being well adapted to act as a cantalirer in use. Fig. 11illustrates another manner of rolling a plate into sub? slanl ialiy Vshape, with rounded apex instead of flat as shown. in Figs. 3 and 4,thus saving work in the final die forming operation. Referring to thedrawings in detail, the numerals 1 and 2 indicate rolls for forming! myimproved plate, at least one of saiol rolls having an annular groo" 3concaved ventrally as at 4 to form the lishing pass through which thebar 5 is passed, the coneaved portion 4: of {he pass ri'irzning on thebar it passes l'ie'cween the rolls a thickened or convex portion as at(3. In this manner a. fiat bar or plate is formed, thick enod or eoniexed centrally on the face of the plate throughoutthe entire lengththereol The finished bar is then. out into the desired lengths andpressed between form ing dies 7 and 8. the upper die 7 being the malehaving the rounded projection 9; and 8 is the female die having atrough-shaped depression 10.

in forming ear stakes or the like, the male die is raised so that theplate which has been rolled of forms shown in Fig. 3,v

4 or 11 is inserted between the dies; the dies are then pressed togetherand assume the position illustrated in Fig. 7 thus forming a stake orbrace of trouglrshape with in- (lined sides 11, flanged edges 12, and athickened apex portion 13.

The stakes are attached to the ear sides by means of rivers as indicatedin Figs.

1 and 5. These stakes may be constructed in various forms as illustratedand indicated by the numeral 17 in Fig. 1, with an outwardly extendingflange at the top and the lower part of the rib tapered; or as 18 inFig. 10, with the rib tapered from an intermediate portion of the staketoward each end, or as 19 in Fig. 2 where the rib is of uniform sectionthroughout its length.

The end braces or other stifl'eners may also be made in slightlymodified forms as indicated at 20 in Fig. 1 where the brace is ofuniform section throughout its length; or as 21 in Fig. 8 where the ribtapers from the center of the brace toward each end with a straightflanged attaching face; or the ends of the brace 22\may be offset as at23 in Fig. 9 to fit over a corresponding projection on the car.

In Fig. 11 I have illustrated another form of a finished bar 16 which'issubstantially V shaped in cross-section with a rounded apex. These ofuniform section throughout their length may be formed either by passingthe bar between rolls, or by pressing as illustrated iif Fig. 7.

Although I have shown and described my invention in conside'able detail,I do not wish to be limited to the exact construciion specified, but mayuse such Substitutions. modifications 0r equivalents thereof, as areforms of stifi'eners which are embraced within the scope of myinvention, as pointed out in the claims.

Having thus described my inventioinwhat I claim and desire to secure byLetters Patents is 1. A stillener for a car wall, comprising a taperedtrough-shaped member provided with outwardly extending i'ree edges, anda thickened integral apex portion.

Q. A still'ener for ear 'alls, comprising a tapered lrouglrshaped memberprovided with an integrally thickened apex portion.

3. A still'ener for car walls. comprising a trough-shaped member havingits greatest height intermediate 01' its ends and gradually decreasingtherefrom. said troughshaped member being provided with outwardlyextending flanges. and a thickened integral apex portion.

r. still'encr for a car wall. comprising a trough-shaped membergradually-decreasing in height from an internualiate part to ward itsends. said trough-shaped member being provided with a thickened-integralapex portion, and a llange extending entirely around its edges.
